Here is the original table that's being updated in this series: th-cam.com/video/IQfklF8btTA/w-d-xo.htmlsi=E3amINKqjGxdXD4_
Ohhhh Myyyy Gaaaaaaawwd! HES BACK! I'm so glad you are still improving your designs and sharing with us!
I love it when channels that went dormant suddenly pop up again years later
I'm delighted that you haven't given up on this idea as it's still sitting close to the top of my build list once you have something that I can build from. Keep on going Scott!!!
Every time I watch one of you videos, I really want to build this table. I don't think I have the time, money, willpower but really enjoy your videos. Hopefully it won't be another few years before the next
I came back to this channel so often in the hope of an update. Thanks for the video!
7:40 you know they actually make reusable zip ties that have an extended ratcheting tab you can push on and release
Such a impressive Brilliant design! Cool!!
Great to see you! Perhaps some 3D printed or delrin pads used as gibs for adjustment screws could help. Great work!
Great update and explanation, thank you. I'm sure you've already considered this but I'd probably use 4 lifting ramps in the final design. Just thinking about end users that like to rest their elbows on the edge of the table
13:30 set screws for the vertical rails: you can get set screws with ball bearings in the end, that may reduce the risk of galling.
Wow. An even better design. A lot of work. It really is coming together.
I was hoping this project would drag you back in eventually. Your process is a blast to watch.
Totally agree about the zip-tie! I am unashamedly OCD in so many ways! Keep up the good work Scott!😁👍🤙
I subbed when I saw the original table design in action way back when. Glad you're still thinking about it and wanting to improve the design. This is all fascinating to me!
Impressive work! I’m amused how 20 years later and we’re still fascinated trying to replicate the DB Fletcher Capstan Table, which was based off Robert Jupe’s patent from 1835!
Welcome back!
Welcome back! Love your work.
Great work incorporating the latest resources to improve 👍😎👍
you are back! so happy now! Looking forward to all your creations!
Great! Nice to see your stuff!
really great to see an update from you! thanks
can't wait to see the result. Cheers
What will you use for the final lifting ramps? You stated that you 3D printed them due to difficulty machining them, but clearly 3D prints will not suffice long term. I ask because those hardened bearings running on anything softer than steel will gall the material over time and be a major point of failure once the full weight of the top is applied. They're going to have to be machined and machined out of steel. How will you resolve this?
Doesn't seem like a terribly difficult part to have machined
He could use a bearing/roller with molded polyurethane over the outer race. Then the lifting ramps could be molded, in production, by a simple plastic casting process. No machining required.
To make the casting, start with an SLA 3D print of the part (to get the best surface quality and dimensional accuracy). Lightly sand the SLA print to achieve the desired surface finish. Use this at the master part. Then create 2-piece silicone mold/s for the part. Suspend the part in a simple leak-prove wood box, and add a sprue to fill mole w/ resin later. Pour in 2-part silicone mixture. When cured, use sharp knife to cleanly cut master part out of the silicone. Then pick your favorite 2-part resin, reassemble the mold, pour the resin it into the mold, and wait for it to cure. This method will create about 3 parts per day per mold. The mold will last for about 20 - 30 parts before needing replacement. Ramp up production by adding more molds, using the same master part. If done well, this can result in a plastic part nearly identical in quality to an injection-molded parts, without the high expense of an injection mold. This method works well, at reasonable cost, for 10s and several hundred parts. There are companies that will mold these parts. By that time you should know if it is worth the investment of injection-molding the parts.

Send Cut Send is awesome!
Why are the arms that connect the center ring with the 4 slides that rise of a different shape near the center ring than the arms that slide out the panels whose vertical height remains constant? Was there merely a design change to permit all 8 arms to fit when the table is in its small state? Thanks.
Brilliant
Thank you Scott 👌!
This is absolutely beautiful. I’m so glad youtube suggested this video.
Nice.
great!
You're back! 🎉
Been eagerly awaiting this update.
The new mechanism looks so promising! Excited to see the development!
Damn dude, you're back! Nice!
If you could deliver it to my home, what would the prices be?
Woah 😮😮
You’re a genius!
Great video. First time viewer, so I’m fascinated with your mechanism, but you never showed or discussed what you are trying to do. Maybe other videos might show, but it was a little downer not to know what we awe really doing or why.
I added an info card and pinned a link now, here is the original design we're updating: th-cam.com/video/IQfklF8btTA/w-d-xo.htmlsi=E3amINKqjGxdXD4_
Good lord it’s been a while. Welcome back!
Here we go again. Just take my money. I destroyed my garage trying to build the last one. This design looks very precise.
Ha! Just last week I looked up your name to see if I’d missed any videos - great to see you back
Still haven't my "standing desk"
"it can't be.. is that ... OMG"
Good afternoon, my name is Luis Alberto José Mendoza, I am sending this message from Mexico. I would like to buy your aluminum akpareser base, the one that has 8 arms or 8 extensions. I would like to know its price.
Project Mahoraga
Looks good; but what the heck does it do??
That's a good question, hah, I never showed the original concept that I'm upgrading: th-cam.com/video/IQfklF8btTA/w-d-xo.htmlsi=Zg5x1ZdIvoTinW8G
Just saw this video. What is this thing for?

@@ScottRumschlagthanks for the reply. Impressive.
Cool design! I think you should add into your videos title and description the subject. New mechanism of what. More ppl will find your valuable content.
Oversight on my part, I added an info card and pinned a link now, here is the original design we're updating: th-cam.com/video/IQfklF8btTA/w-d-xo.htmlsi=E3amINKqjGxdXD4_
So, you're basically reverse engineering the "fletcher-capstan" table?
no..he's making a base kit so that every wood worker can make one themselves now.
Someone send this man a metal 3D printer and four axis CNC machine! Billionaires? Where are you? Stop sitting on your yachts and do something useful.
